Give it a chance!! I have been taking Lyrica for 2 years now. I take it to help with nerve pain caused from an accident which caused numerous spine fractures and damaged nerves. It has been a life saver. The foot burning, tingling and shooting pains have subsided. Not gone but far better. When I tried to stop taking it the nerve pain increased tremendously. No weird nightmares, no weight gain, no side effects. My limited activity is due to back injury but I have found swimming to be wonderful and it does help with the weight. When you are in pain you don't exercise. Exercise and give Lyrica a chance. It took months to regulate the dosage I am on now. (3oo mg daily) Everyone is different. Most of you sound like you are on plenty of other meds too. Are you sure they aren't causing your side effects??
